Abstract (en)
[origin: US6160063A] A catalyst composition that is the combination of or the reaction product of ingredients including an iron-containing compound, an organomagnesium compound, and a cyclic hydrogen phosphite. This catalyst composition is particularly useful for polymerizing 1,3-butadiene into binary cis-1,4/1,2-polybutadiene.
